Description

Eccentric pull rod assembly and laminating machine using same

Technical Field

The utility model relates to a laminator especially relates to the draw bar assembly that the laminator was used and is provided with this draw bar assembly's laminator.

Background

The photovoltaic module is developed along with the photovoltaic module production industry, the specification of the photovoltaic module is larger and larger, the development of a photovoltaic module laminating machine to large-size multilayer is promoted, at present, the width of a single machine of the laminating machine is 2.3m to 2.7m, the length of the single machine of the laminating machine is 3.6m, 8.7m, 9.4m, 11m and other specifications, the weight span of the transmitted module is increased, the range is from 100kg to 500kg, the requirements on chains are higher and higher, the chains can meet the normal working requirements only when reaching at least 16A and above specifications, and therefore, the pitch of chain pieces is increased. The tie rod assembly is an important part of the laminator for transporting the photovoltaic assembly, and the weight of the photovoltaic assembly is mainly borne by the tie rod assembly in the transporting process, so the requirements on the strength and the deformation resistance of the tie rod assembly are higher and higher. In practice, in order to avoid the situation that the pull rod assembly bends up and down and deforms left and right due to bearing in the process of conveying the photovoltaic assembly, the strength of the pull rod assembly needs to be continuously improved, and two methods are used for improving the strength of the pull rod assembly, namely, the width of the pull rod assembly is increased, and the thickness of the pull rod assembly is increased. Under such conditions, in order to increase the strength of the tie rod, the tie rod assembly is generally widened. However, the widening brings with it also some technical problems: because the laminator has upper and lower two circulation drive mechanism, and upper circulation drive mechanism is for driving high temperature cloth, makes high temperature cloth cover on photovoltaic module, prevents that the glue from gluing on the silica gel board of suppression usefulness, and lower drive mechanism is used for driving photovoltaic module, like this, in limited space, need arrange two upper and lower pull rods side by side. The pull rod assembly with the prior art structure comprises a pull rod body, sleeve rod fixing seats for supporting and limiting the sleeve rod are arranged on two sides or one side of the pull rod body, the sleeve rod is locked in the sleeve rod fixing seats by bolts, pull rod lug seats for connecting with a chain are respectively arranged at two ends of the pull rod body, fixing holes are arranged on the pull rod lug seats and fixedly connected with the chain fixing seats arranged on the chain through the fixing holes, the fixing holes are generally symmetrically arranged relative to the length central line of the pull rod body, in order to prevent the upper pull rod assembly and the lower pull rod assembly from generating interference when meeting, in the actual structure, the positions of the pull rod assemblies in the upper and lower circulating transmission mechanisms are staggered, as shown in fig. 1, because the pull rod body 1 is rigid and is rigidly connected with the loop bar fixing seat to have a certain width, when the upper and lower pull rod assemblies pass through the chain wheel and the roller, the turning radius of the upper and lower pull rod assemblies can be changed along with the different turning radii of the turning positions of the upper and lower pull rod assemblies, the turning radius of the upper and lower pull rod assemblies is larger than that of the chain when the upper and lower pull rod assemblies turn, and the operation of the upper and lower pull rod assemblies in the circulating transmission is asynchronous, so that high-temperature cloth dragged by the upper and lower pull rod assemblies is relatively moved, the back of the assemblies is dirty, and the manual cleaning difficulty and the working hour are increased; in addition, the turning radius is suddenly increased at the position of the chain wheel and the roller, so that the high-temperature cloth is dragged, the high-temperature cloth is easily torn when the roller passes through, the high-temperature cloth is prevented from being torn to be broken, the allowance of 2-3cm is remained in the common high-temperature cloth, and the high-temperature cloth is long, the tail part of the high-temperature cloth is stacked, and the high-temperature cloth is easily abraded.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an aim at to the pull rod assembly of prior art structure its turn radius is big when the turn and different positions department turn radius of chain cause about the high temperature cloth drive mechanism operation asynchronous, cause the high temperature cloth to produce the drunkenness for the photovoltaic module surface, make the photovoltaic module surface receive stained not enough, and because turn radius is big than the chain when the turn, it needs high temperature cloth to cause to drag high temperature cloth to have the surplus to the high temperature cloth, high temperature cloth surplus makes and causes the high temperature cloth to drag when the pull rod assembly is in sharp operation and draws the not enough that causes high temperature cloth wearing and tearing, an eccentric formula pull rod assembly and laminator are provided.
